'MACHINE FOR OBTINING FIBRS FROM FIBER-BEARING SUBSTANCS.

SPECIFICATION forming part of Letters Patent No. 292,240, dated January22, 1,884.

y Application ledNovembcr 17, I1883. (No model.)

To @ZZ whom t may concern:

Be it known that l, E. Louis Lown, Jr., of vthe city of Brooklyn, in thecounty of Kings and State of lNew York, have invented a new l and usefulImprovement in Machines for Obtaining Fibers from Fiber-BearingSubstances, of which the following is a specification. Y

My invention relates to machines for obtaining fibers, in which arecombinedabed or con- Io 4cave and a rotary cylinder arranged above andin the bed or concave; and it consists in various novel features in theconstruction of many of the parts of 'such machines, and in the manner4of combining the -parts together, all' as I5 hereinafter described, andas set forth in the claims.:

f l In the accompanying drawings, Figure l is fa side'elevation of amachine embodying my invention.-v Fig. 2 is a vertical section in a 2oplane transverse 'to the axis ofthe cylinder v and just within one ofthe side frames ofthe machine, and Fig. 3 is a plan of the machine.Similar letters of reference designate corresponding parts in all thegures.

The principal working parts or members of .themachine are a bed orconcave, A, of approximately semicircular shape, and a cylinder, whichis of approximately circular shape, although it may varyA somewhat froma true 3o cylinder. The bed or concaveA, here shown,

iscomposed of a main or principal portion, which extends beneath thecylinder and upward on the delivery side ofthe machine, and which is xedin position, and an adjustable 35 portion or section, A', whichisattheentrance side of the machine. By,'entrance side77 vI mean that sideon which the plants or other materials to be operated on are introduced,and by delivery side I mean that side on 4o .which the plants ormaterials leave the machine after being operated upon.

, B designates the side frames of the machine. They are provided ontheir inner sides with segmental anges or ribs a, to which the staves b,which form the fixed portion ofthe bed or concave, are secured by boltsc. b', which form the adjustable portion A of the concave, are securedto curved supports c, which are hinged at a2 tothe side frames, B. 5oThe said adjustable portion A is held in place by screws d, which fit innuts d', secured to The staves on opposite sides or faces with grooves,and

Vthrough these lugs or ears and the heads vor screws vthe adj ustablesection A maybe moved or swung to vary the distance between it and thecylinder, and this without moving the main or principal portion of thebed or concave. The cylinder comprises a shaft, C, heads or circularsupports C', secured on the shaft, and staves e, which are secured tothe iianges c of the heads or supports O' by bolts e2, andA which formthe working-surface of the cylinder.

The staves b b of the bed or concave and the staves e of the cylinderare shown as provided are reversible, so that either side or face may bepresented outward for use. They maybe unbolted from their heads orsupports C', reversed in position, and again secured in place. As shown,the 4grooves in what are n'ow their inner sides or faces areof finerpitch than the grooves in what are now their outer sides or faces, andthis construction may render them better adapted for operating upondifferentA materials. Even if the grooves or projections on both sideswere of like pitch, the staves would be susceptible of longer use, forwhen one side became smootlithey could be reversed in position.`

' In the cylinder are pockets or cavities C2, of 8o which there may beone or more', two being shown. A description of one will apply to both.4

In the peripheries of the heads or supports C are depressions orrecesses f, and in these is seated or arranged an adjustable section. ofstave, C3, which may be of metal. As shown, it is provided with lugs orears f', and is hinged to the heads or supports C by a bolt passing 9osupports. It may have a smooth surface, or its surface may be grooved orroughened.

. At each end of the stave or section C3 is a bolt orscrew, f2, having anut, fiwhich'is fitted and held against movementV lengthwise of thescrew in a recess in the flange e of the head or support C. As shown,the nut isv concave lengthwise of the screw, and the walls -of therecess which holds it are convex; hence .the nut .is not .onlycapable ofturning, but

roo may swing slightly in its recesses, to accommodate itself to thevarying angles at which the "the flange and entering the side fraaie.

screw will extend as the stave or section C is moved inward and outwardby turning the nut.- By moving the section C3 in or out relatively tovthe center ofthe cylinder the size of the pocket or cavity C2 isincreased or diminished in size. The pocket or cavity C2 greatlyfacilitates the introduction of material into the machine, as it affordsan increased space between the cylinder and concave when the said pocketor cavity comes to the entrance side of the machine.

D designates the boxes or bearings for the cylinder-shaft C. They reston the side frames, B, and are each provided with lateral extensions Dand a downward]y-extending arm, D, in which is a slot, f/.

Through the extensions D/ extend bolts g', which pass through slots g2in the side frame, B, as shown dotted in Figs. l and 3, and have springsg3 applied to them above the boxes. These springs hold the cylinder downwith a yielding force, but still permit it to rise. Setscrews gt,inserted through the extensions D and impinging on the top of the sideframe, B, limit the downward movement ot' the box and cylinder.

Through the slotted arms l)' are inserted bolts g5, which guide theboxes in rising and falling, and the lower one ot' which limits therising movement by reason of the lower end of the slot g coming againstit. The two bolts g5 aid in steadying the box and preventing its cantingwhen it is raised off its seat on the side frame, B.

For operating upon different materials it is desirable to vary thedistance between the cylinder andbed or concave at the ent-rance anddelivery sides of the machine, and this is effected by shifting theboxes D horizontally.

In the side frames, B, dare three sets of holes, g, for the bolts g5,thus providing for different degrees of adjustment of the cylinder.These holes are shown in Fig. l, the bolts gi being screwed into oneset.

Upon the shaft C of the cylinder is a spurwheel, E, which receivesmotion from a second wheel, F, on a shaft, F', and the shaft F receivesmotion from awheel, G, secured upon a driving-shaft, G, and gearing withthe wheel F.

On the shaft G is a pulley, G2, for a drivingbelt. Obviously the shaft Gand wheel G might be dispensed with, and the pulley G2 placed on theshaft F, but the motion imparted to the cylinder would not be so slow asit now is. \Vhcn the cylinder is shifted horizontally, the shaft F mustalso be shifted to maintain the wheels E F in gear. In this example ofmy invention I provide for thisI by mounting the shaft F ineccentric-boxes, l1, which are fitted and adapted to turn in seats orholes h in the side frames, B. Each box has a fiange, and is securedagainst accidental turning by a bolt, 1', inserted through B turning theboxes h a quarter of a turn, thd

shaft F and the cylinder may be shifted, so that the bolts gf will enterthe middle s et of holes, g, and the boxes are then secured by insertingthe bolts l.' in either of two holes, t i, in the side frames. Vyturning the boxes half aturn, the shaft F and cylinder may be shifted,so that the bolts r/f' will enter th'e set of holes g, farthest to theleft in Fig. 1, and the boxes h are then secured by inserting the boltsi in holes Ai2 in the side frames, B. The shaft G is also mounted ineccentric-boxes 71, like those above described, secured in a like mannerin different positions.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-
